[compiler-rt] [scudo] Remove malloc_enable_child from API. (PR #215439)

[Christopher Ferris via llvm-commits]

https://github.com/cferris1000 created https://github.com/llvm/llvm-project/pull/215439

The malloc_enable_child does not need to be a public API, instead move the function to be static and reference it that way.
